• True

• False

What is the purpose of forming an alloy?

Answer explanation

The purpose in forming an alloy is to provide a material/substance that are different from its components. The mixture is done according to the needs of the industry.

In most cases, the alloy is chemically more (a)   than each single component. In fact, alloys are designed for specific resistance to corrosion, or temperature.

Stainless steel iron are a combination of

• iron, chromium and nickel

• iron and chromium

• iron and nickel

• iron, nickel and carbon

The combination used to make stainless steel is particularly good because it is resistant to (a)   .

Super alloys of nickel and cobalt are used in aircraft engines due to their corrosion and (a)   resistance.

Solder is used for:

• gears

• aircraft frames

• jewellery making
